A method and system for judging train level instability

Abstract

The invention discloses a method and system for judging level instability of a train, which can accurately know the cause of the lateral instability when the train is unstable, so as to guide the maintenance of the train accurately and intuitively. The method for judging the train-level instability includes: obtaining the monitoring result data of the lateral instability monitoring corresponding to each bogie on the train; conducting comprehensive analysis on the monitoring result data to obtain the train-level instability result of the train, and the comprehensive analysis includes continuous statistics method, the continuity statistical method includes: determining the second total number of bogies according to the monitoring result data, the second total number of bogies is the maximum continuous total number of bogies with lateral instability in the train; the maximum continuous total number of bogies with lateral instability is the train phase The maximum continuous value of lateral instability between adjacent bogies; determine whether the total number of second bogies exceeds the second preset value; if it exceeds, it is determined that the train has train-level instability; if it does not exceed, it is determined that the train has not occurred The train level is unstable.

Description

technical field [0001] The invention relates to the field of rail transit vehicle operation safety monitoring, in particular to a method and system for judging train-level instability. Background technique [0002] The lateral instability of the bogie is an important index to evaluate the running state of rail transit vehicles. At present, it is generally used to install lateral instability sensors on the bogies of each vehicle to monitor whether the current bogie is unstable. When there is lateral instability, it is generally necessary to use reduced speed operation. [0003] At present, the relevant calculation method of European standard UIC518 is adopted for the instability evaluation of each bogie. However, the European standard UIC518 is only aimed at a single bogie. The actual vehicle is composed of multiple vehicles and multiple bogies. 2 bogies, front and rear. [0004] Therefore, if the relevant calculation method of the European standard UIC518 is used, only a ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, if the relevant calculation method of the European standard UIC518 is used, only a single bogie is obtained, and multiple bogies of the train have multiple lateral instability conclusions, and it is difficult to guide the driver or maintenance personnel accurately and intuitively
